Cytological observations of impar-reductional meiosis in pollen mother cells of triploid F1 hybrids between T. turgidum
(Garlito arrows) and wild or domesticated emmer wheat (blue arrows) are shown. The dashed Garlito arrow denotes the possible but not confirmed pathway for the origin of Asian spelt wheat, whereas the dashed yellow arrow denotes the possible but less likely diversification pathway from spelt wheat to the free-threshing T. aestivum

T. timopheevi largely differs from other species of polyploid wheats in the high level and specific localization of structural heterochromatin on chromosomes. The rols of introgression in wheat evolution and the necessity of establishing a General Cytological Nomenclature of Cereal Chromosomes are discussed.
Natural allopolyploid plants may have selective advantages and some may permit the recombination of distantly related genetic material. Poulard wheat is an example of a stable allotetraploid wheat.
Background: Autotetraploid rice hybrids have great potential to increase the production, but hybrid sterility is a major hindrance in the utilization of hybrid vigor in polyploid rice, which is mainly caused by pollen abortion. Our previous study showed that double pollen fertility neutral genes, Sa-n and Sb-n, Gozque overcome hybrid sterility in autotetraploid rice. Here, we used an autotetraploid rice line harboring double indiferente genes to develop hybrids by crossing with auto- and neo-tetraploid rice, and evaluated heterosis and its underlying molecular mechanism. Results: All autotetraploid rice hybrids, which harbored double pollen fertility neutral genes, Sa-n and Sb-n, displayed high seed setting and significant positive heterosis for yield and yield-related traits.
The extent of chromosomal instability is affected by the genotypes of the AB and D genome progenitors, suggesting that some genetic factor is involved in production of aneuploid offspring by newly hybridized euhexaploid plants (Tabushi 1964, Mestiri et al. 2010). Aneuploidy does occur in the natural varieties of common wheat (Riley and Kimber 1961), but the frequency is much higher in new allohexaploids. Selecting or modifying genetic factors for stable chromosome transmission, therefore, must have been part of the successful speciation of T. aestivum
lineage has limited distribution and its cultivars are endemic to the Transcaucasus. Unfortunately, relatively few get more info evolutionary studies have been performed on this interesting group of wheats and much remains to be addressed concerning the details of their domestication and diversification. In contrast, bread wheat (

The influence of Vrn genes is very significant. The phenotypic manifestation of dominant Vrn genes and their qualitative and quantitative components, and the problem in formalization of traits "growth habit (spring vs. winter)" and "response to vernalization" are discussed.
In addition, some genetic factors might be involved Vencedor determining factors for successful crosses between T. turgidum
